Mount Nebo is crowned by three peaks, with the northern peak reaching 11,928 ft (3,636 m). Original surveys placed the southern peak as the highest at 11,877 ft (3,620 m). When the mountain was resurveyed in the 1970s and the northern peak was found to be the highest, two substantial trails already led to the south summit. Parts of the mountain are covered in snow from mid-October until July. It is a popular, although strenuous, destination for hikers from the nearby towns of Nephi and Provo, Utah.

The Mount Nebo Scenic Byway, a National Scenic Byway, departs I-15 at Payson and climbs to over 9,000 feet before rejoining the interstate at Nephi. The route features panoramic views of Mount Nebo and the Utah Valley and Utah Lake far below. There are numerous trailheads along the route for the hiking enthusiast including a short walk to the "Devil's Kitchen", an area which has been described as a "mini Bryce Canyon".
